Low voltage disconnect circuit

Publication Date:  2012-07-24 Views:  36 Downloads:  0
Issue Description
Equipment is UA5000. Version is UA5000V100R011B02D082
Power model is Power4845
RT(Remote terminal) works on the AC power supply and whenever AC supply goes off it works on the battery banks. 
RT should be shut off when it detect the voltage below the threshhold value to prevent the battery from discharging below threshold.
Alarm Information
Voltage goes below the threshhold value.
Handling Process
We tried with the command:
       power off load-off-state permit load-off-voltage 42 battery-off-state permit
       battery-off-voltage 41.
 
      Test was successfully done. RT was shutdown at 41V.
Root Cause
We tried with the command 
      
            Power off battery-off-voltage 41
But it didn't work and RT was still working below 41v
Suggestions
Now the RT shuts down as voltage drops below the threshhold.
